Abstract: Considering the dynamic wireless charging mode of electric vehicles, an adaptive control algorithm is proposed to optimize the charging power of electric vehicles and the power supply ratio of the power supply sources. In the cost function, the charging satisfaction of the electric vehicle users, the load burden of a wireless charging road, the power supply cost and the power supply stability are comprehensively considered. Through an adaptive dynamic programming (ADP) algorithm, neural networks are trained to estimate and minimize the long-term cost function, and an approximate optimal control strategy is obtained. Simulation results show that the proposed method can take into account the user's charging satisfaction and load burden of the charging road, while meeting the requirements of power supply cost and stability.
